HMI on CC LINK IE FIELD

7 posts in this topic

Hello all,

kinda lazy question, but I'll rather ask, before I'll went to deep into HMI scripting.

Because of a design of CC link, there are RWr and RWw

Is there any simpler solution for displaying value stored in PLC, while also letting HMI operator change the value and save it to PLC, than scriting in HMI?

hope it makes sense to you

thank you in advance

Why don't you just use the Ethernet driver instead ?

its part of long CC link chain, it would mean extra cable through line

Which HMI is it?  Likely the connection manual for it would show how to access controller data.  I don't think you are limited to the read and write words, i think there is messaging capability, but have never put an HMI on a field level network before, only serial and Ethernet.

HMI should be on Ethernet, not a field level network.  Makes life so much easier.
